If you wonder where people get their inspiration from when they build bosozoku scale models and RC cars, this video by take4mickey is a good example:
The Number 34 Soarer in small and extra large size!

On this picture while unloading the car you can see its profile a bit better:
Perfect Tomica Skyline RS immitation
If you pay good attention and compare it to this picture of the real car (posted before here) you can see that my remark was a bit off:
The real Hashemi Tomica Skyline RS Super Silhouette
I remarked that the wheels were too small, but that is not the case: the real one appears to have a much higher roofline. This was done to comply to the rules of Group 5 which required to retain the roofline of the car. Other parts were allowed to be altered as long as the silhouette remained the same. Hence the lowered bonnet, fenders and trunk.
